To all whom t may concern .j

Be it known that I, CHARLES IIAUSMANN, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have made and invented certain new and useful Improvements in Scales, of which the following is a specilication. t

My invention relates to a scales and particularly to that type known as a balance.

The object of my invention is to provide a scales which will be neat and attractive in appearance, simple and efficient in operation, may be economically manufactured, and. at the same time an instrument of precision suchas may be used for comparatively fine weighings" such as used for the determination of the size of diamonds.

A further `object is to provide a scales which is of the balance type, is readily portable to the extent of being housed within a box or casing which may be carried in the pocket.

A further object is to provide a scales of the aforementioned character having iinproved means vfor yraising and maintaining.

in a raised position, the fulcrum and the beam, the mechanism whereby this is carried out beingsimple in construction'and particularly convenient and accessible for' its operation. n

With the foregoing and other objects in view, my invention consists in the improved" scales illustrated in the accompanying drawing and hereinafterdescribed and claimed,

and in such variations `and modificationsy thereof as will be obvious to those skilled in the art to which my invention relates.

In the'drawing accompanying and forminga part of this specification and whereinI lthe preferred embodiment of my invention is illustrated: i

Figure 1 is `a view .in front elevationof my improved scales Figure 2 is a view in section taken on the tion of theraising lever, `thefulcrum and fulcrum support being in lowered'position,l 1,-'

freely swing and the desired weight measurements to be made. 4 J n e u Iieferring specifically to the several views wherein similar reference numerals desig- `nate"corresponding parts throughout, a box or casing 10 is provided' with the hinged lid 11 anda strut 12 which is liingedly secured to thebox and engages the lid and is adapted lto `hold it in an upright position.

arm 15. n Slidably mounted` upon the base plate is ythefulcrumv support 16 which is provided `withthe slot 17 therein through which ex- `tends the slidingmovement of the fulcrum sup- `portand holding i the retaining screw 18,l thus limiting v itin position' against the base plate.,` kThe lower extremity of the fulcrum, support isv cylindrical in cross section as at19fandI extends through a suitable opening .20 formed in they outstanding `The fulcrum support .carries the fulcrum 21atits upper extremity, whichin turn supports thefscales beam 22: in the usual manner..r Suitable pans 23,. are securedto the scales beam and vthe various connections preferably carried out by suitable Vknife blades, as is customary in instruments of this character.

Mounted `upon the fulcrum support rodis the dial 24, over which travels the indicator t securedzto the scales beam. The indicator 25 extends `through an `opening 26 in the fulcrum, `which is sufliciently large sof as to allowtheindicator to swing freely and thus indicate'the extent ,of 'oscillation ofthescales beam. The cords by means of `which the pans are ylength' that whenfthe fulcrum support is in suspended. are J of such its lowered' position and resting upon the shank of theretaining screw 18, the vpans will rest upon-the.supporting `surface upon which the casing l0 is located. y i

In `order toY raise `thewscales beam and maintain it in its raised position, I have providedy the outstanding bracket and downwardly projecting jarm 15 with the slot 27 and between the walls of which is pivoted The outer and projiu `with the downwardly extending and offset truding extremity of the lever is provided with the thumb-engageable knob or projection 29, while the inner extremity is provided with the cam raising Jface 30 and with the otliset locking end 31. The raising face BO extends so `that the normal thereto will approximately include the ulcrum support 19, while the offset locking end 31 is provided with the tace 32 having the normal thereto extending approximately through or above the pivotal mounting of the raising lever. The pivotal mountingof the raising lever is located so that when `the 'tulcrum support and the scales beam are in their lowered position the raising Alever will `ex,- tend substantially perpendicular to the fulcrum support. As the outer extremity ,of the raising lever is depressed, the ulcrum support is raised, the end of the rod 19 travcling along the cam face 30 and being raised therewith until the otl'set end 31 Ais reached, whereupon the further depression of the raising` lever brings the cam face 3 0 .to a stop against the lower surface 33 of the bracket and allows the extreme end of the rod 19 to pass a slight distance down the locking end 31,. The downward force exerted by the tulcrum support will then pass through or above the pivotal mounting of the raising lever and which, in connection with the slight jamming action whereby the rod 19 is moved against the base plate, causes a self-locking action to take place and the tulcrum support and fulcrum to remain in an elevated position until such time as it is again desired to lower them, whereupon the outer extremity of the raising lever 1s raised, releasing the rod 19 from the otlj'set` end and allowing it to again travel down the cam face 30 as the raising lever is returned to its normal position, whereby the ulcrum support is lowered and again rests upon the retaining screw 18 and the scale pans upon the supporting surface.

The housing 10 isy adapted to receive the scales beam and pans therein, so that the entire apparatus is adapted to nest within the housing 10. A suitable catch 34 is provided whereby, atter the strut 12 has been un'fastened Jfrom the lid and the lid moved into its lowered position, the latch will lock and hold the lid in a closed position.

My improved scales as thus constructed embodies a minimum amount of raw material, maybe economically manufactured, will be durable and emcient in service, as well as precise in its weight measurements, and particularly convenient to operate, due to the readily accessible ulcrum raising lever and its ability to maintain the scales beam in its raised position.

Having thus described and explained my invention, 1 claim and desire to secure by Letters Patent:
